Preparation and characterization of Al<sub>2</sub>O<sub>3</sub> bulk aerogel with high specific surface area and low density

We report a facile approach to synthesize alumina aerogel through sol-gel reaction followed by supercritical drying, in which ASB is as co-precursors, EtOH as solvents, Etac as chelating reagent, HAc as catalysts. The as-prepared aerogel was treated at different temperatures.Moreover, the effect of...
